@PWill: Lame, he was trying to start a discussion, and you come with lolcats?

I think what he is saying is that we are not as free as we think, because we are being manipulated. I think it depends, if you are economically very dependent on your job, you may be forced to take any job open to you. But i think many people do have freedom to leave their job and find another without going hungry, not being able to pay rent, etcetera. However I think job-centeredness is a caveat of capitalism.(some other here, not sure i covered them all, though)
But the fact is that capitalism is closest to something that works yet, so the caveat must be dealt with somehow, this is usually done by governments.(and IMO works quite well for governments that are reasonably corruption free)

That said, i do not think prostitution equals slavery. It just could, just like any other job the job-owner does not make enough money on. Slavery is horrible and often includes prostitution, but it does not equal it.
I am not against prostitution/porn, but i think there should be some kind of registration, and prostitute-passport. To make sure it is done morally. More things should be a separate (much)higher minimum wage, requiring organizations of it to be non-profit, and open.(including non-prostitute paychecks)

I believe there was also an aspect of manipulation, unability of self control in your post. Ill assume that you do not mean lack of economic freedom, but lack of freedom because manipulated by stuff like advertisements? I am not sure what you mean by this really, i feel perfectly independent on that.(i do not live in the US, though.) I guess some idiots are overly influenced by MTV and such.(retards)

About actual forced slavery as in abducted. Bad. Of course police should investigate, but i do not know what to say about that. Slaves being transported through is a problem in the Netherlands too.(although i have never heard of abductions by them in the Netherlands)
